Just saw the Heidts IRS setup for the 3rd gen Camaro at SEMA. The car they had it on was unbelievable 1,000hp 1990 Camaro completely custom, the car is 3" wider than stock. Just wanted to share some pics and from what I saw the Independant rear bolts right up and looked to be one good looking unit.
The Heidts folks were talking to me about this car intro-ing the new IRS at SEMA, during ThirdGen Expo last spring. I had no idea it would be this badass.

Absolutely, this car is badass! Apparently the car was sold just before shipping out to SEMA, he did not know what it sold for though.
There are issues with the unit. I had a nice long discussion with the lead engineer at SEMA. They haven't figured out how to route exhaust past it yet is the biggest one. The show car dumps the exhaust next to the transmission right now because they ran out of time to sort that out before bringing the car to SEMA. There's also the price point which will put most people out of the market on it. But it's still a work in progress with some additional tweaks being made to try and resolve the remaining issues.
so they built a 1k hp car and custom made/built a irs rear that is only rated to 800hp per their website, then sold it to someone??
seems legit.
either way that is a slamming piece of engineering and a good looking car. the interior is not my taste but that can easily be fixed.
appears to be a significant amount of welding to get that to "connect" to the rear subframe
The craftsmanship on the car is incredible. But some of it is also illegal on a street car and some is against the rules for various sanctioning bodies for a track car so this one will end up in someone's collection and probably never get driven. IE: DOT regulations require amber side marker lights on cars made after 1970 for the US market and they shaved the marker lights. This is a ticketable offense. And the location of the fuel pressure regulator violates some sanctioning bodies for racing. It also lacks a cage which would be recommended for the power level.
There is a bit of welding to do to get the IRS put in. The brackets it bolts to weld through the entire upper portion of the frame in the wheelwell area and then the rest of the IRS bolts to it. With the current design the exhaust is the biggest issue. There is no space for the exhaust to go over the unit without touching the gas tank. There is no space to go through it. And the only space to go under it is directly under the differential and that is limited to oval pipe for ground clearance. Right now I would classify this as a good idea that still has some engineering to do. Then price will become the issue.
In conversation with the owner of Heidts and the engineers they did say the car had already been sold despite not being completed before put on display at SEMA. We'll find out to whom and their plans for it when the magazine article comes out.

I spoke to Heidts at Thirdgen Expo and they said the rear will handle 1200+ hp without a problem, and their will be 2 versions for high and low hp setups.

"Our new IRS provides maximum performance both on and off the track and is available in standard (500HP) and high horsepower (800HP) versions"

Car like this driven to and from shows? Will never get ticketed. Most officers probably won't even realize id once had turn signals on the sides. The front/rear would be more telling.
Just with a glance you'd know this car will never see the track, may never even be seen on the street.
If you took a poll of SEMA cars to see what cars would be street legal, I bet at least half of them would be illegal on the street in some way.

Depends on which set of rules you check to. If you use Federal DOT and EPA requirements, then more than half are probably illegal in terms of emissions tampering. Not including all the other violations you could place on a lot of show cars for lights, lifted trucks without mudflaps, tint too dark, etc. Lots of states and individual officers won't care about any of it depending on their mood at the moment.

Thats my point. Of the things that are illegal, no-one is checking. The side marker will probably be over looked because they simply aren't there any more.
Many states have yearly mechanical and safety inspections.
The first thing they check is the lights. The handbook here in vt explicitly says to check for proper marker and reflectors. True that some stations are less aware than others, but few will pass a car with shaved markers.
I wonder what that setup weighs weighs compared to a stock rear, 12bolt, 9" and a S60.
When a car of this caliber is built, no one cares about "legal".
Its a showcar designed to catch the eyes attention and make you look it over really hard.

There are things such as Show Car/Race Car/Exhibition car insurance that wave the annual inspections in most states.
IL has it, and as long as you send in the affidavit with proof of said insurance you are exempt from emissions inspections.
Nice looking car. Would love to see some skid pad numbers & salom times before and after IRS.
Exhaust doesn't seem to me to be a big deal really, couple of bullet mufflers and dump under the car.
Most of cops I've known pull people over after seeing the driver do something wrong or stupid. The LEO's I've know wouldn't ticket the marker lights unless the driver need to be taught a lesson after doing something stupid on the street. However, YMMV.
Expensive yes but when you consider the cost for an upgrade to a 9 inch, aftermarket brakes, new torque arm, panhard bar and new control arms maybe not so bad.
Personally, I have $4000 into my rear suspension. Figure in the cost of the Koni's, the new springs, spring jacks, my Moser 12-bolt, and my Unbalanced Engineering decoupled torque arm, and I'm easily at $4K. So for me, I am pretty keen on IRS. $7K is HALF the price of the next viable IRS kit.
However the non-routable exhaust is a no-go for me.
